INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

Abstract The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

Proteins Are the basic materials of every body cell. Body cells are constantly wearing out. As a result‚ they are continuously in need of replacement Of the six nutrients group‚ only proteins can make new cells rebuild tissue. By the age of 4 years‚ body protein content reaches the adult level of about 18% of body weight. An adequate supply of proteins in the daily diet is essential for the maintenance of health. The word protein is a Greek derivation and means “of first importance”. Composition

Effect of Protein Intake on Strength‚ Body Composition and Endocrine Changes in Strength/Power Athletes Introduction: Proteins are often called the building blocks of the body. Protein consists of combinations of structures called amino acids that combine in various ways to make muscles‚ bone‚ tendons‚ skin‚ hair‚ and other tissues. They serve other functions as well including nutrient transportation and enzyme production. Adequate‚ regular protein intake is essential because it isn’t easily
